Answer 1

The other answers are useful, but the question remains: why doesn't pip have the older version? Because older TensorFlow versions were not built for the Python version you are running. So pip can't find them.

If you want pip to find them, use a python version which TensorFlow was built for. For example, TensorFlow 1.14.0 was built for Python3.7, as can be seen here.
